Overall, a decent show. However, this show focuses, disproportionately, on reasons for the marital split between Cooper and Billie from Billies point of view. Billie was way too selfish focussing too much on her sexual desire. Billie was the love of life for Cooper who was a thorough gentleman and a devoted husband plus a loving father. No wonder he was completely shattered in season 2 that he was simply not up to the task in dealing with the emotional fallout from the split.
The show writers apparently want the audience to be sympathetic to Billie. Billie deliberately bent the truth about her relationship with Brad when Cooper asked her if she was friends with her ex's. Moreover, she kept Cooper in dark about the intense chemistry they had with each other. However, Billie who had not completely healed from the break up from Brad, used Cooper as a long rebound, till she realized that her and Cooper were not right for each other.
I would grade this show a C+
